Dialog addDialog = new Dialog("Add Student", selections, null, 0, null);
EditField inputField1 = new EditField("Student's firstName: ","");
addDialog.add(inputField1);
EditField inputField2 = new EditField("Student's lastName: ","");
addDialog.add(inputField2);
EditField inputField3 = new EditField("Student's email: ","");
addDialog.add(inputField3);
// Display the dialog and add a new element to the list
if(addDialog.doModal() == 0) {
addElementToList(new Student(inputField1.getText(),inputField2.getText(),inputField3.getText()));
}
}
